The Enhancement of Spontaneous and Stimulated Emission by a Bose-Einstein Condensate
In this paper, an exactly solved model for the emission by N atoms is presented. The spontaneous and induced transition rate obtained, are greatly enhanced by a factor which is proportional to the density of atoms n in the volume (λ is the transition wavelength of atom) and dependent on the de-Broglie wavelength λ B in a more complicated way.
